Thanks for the info. I didn't know that. I had heard that some people got the stock boot to stretch enough but when I looked at the stock boot in person (when it arrived at the parts place) I decided that I may not be able to stretch it enough myself and feel confident that I wouldn't ruin it, so I returned it.

 

well, i actually ordered a 38mm boot right from boyeson, it only took a couple of days to come in. i did have to boil the airbox side boot to fit on the carb and it still was tough. let it sit there for a couple of days on the carb, and it stretches. i didn't even try the rad valve boot, because i ordered one, but try soaking it in boiling water, if u don't want to wait. doing that makes a hell of a difference. boiling is way better than a heat gun or anything else.
